So, what does this new update mean? Basically once the email has been told to come back at a certain time and it disappears from the inbox, you can go to that email (either in the sent folder or in “All Mail”) and easily change the return date.

Plans change, especially in busy offices. Maybe you suddenly don’t need the agenda tomorrow, but urgently at the end of the week instead? Or maybe you don’t need to see an email anymore and you want to cancel the return command in Boomerang? Now you can easily adjust the return date to keep things the way they should be. No fuss, no stress.

Another small change is that messages which are returned to your inbox are now labelled “Boomerang-Returned” which makes it easier to see which ones have come back, as per your request. This option can be switched off in the Boomerang options, if you don’t want it.

I came across this post because I searched for Gmail productivity tools. Boomerang has its pros and cons. Thanks for providing good information on that topic. On a related note I recently subscribed for a product called PolitePersistence (www.PolitePersistence.com) because I need an easier way to follow up with people. PolitePersistence does email follow up automatically so the user doesn't have to search for emails later to follow up.

Boomerang is great, but you can only schedule 10 messages a month (without paying for a 'pro' account). mxHero Toolbox seems to have the same functionality without limiting the number of messages. Worth checking out.

I've tried mxHero Toolbox but some messages didn't return for me, and the interface looks as if it could do with a serious design overhaul. I'm happy to pay to support Boomerang because it has been proven to work and I can rely upon it.
